We couldn't just count down the coolest Android smartphones, so we've rounded up five awesome Windows 8 concepts, starting with the ultra sleek Nokia 8. Others include: the Windows Phone Apollo, Surface Phone, and lots more. Continue reading to see them all.

5. Windows Phone Apollo

The UI is created with the idea of an infinite canvas, so there's no need to be limited by the screen. This render brings us a new lockscreen, that allows you to choose clock size and position, type notifications and weather settings. Landscape mode is also supported, a feature that I really wanted for a while now and that fits the Windows 8 look that will come in the future.

4. Surface Phone Tablet

If you want specs, know that Jonas envisions a quad core CPU inside, maybe a Tegra 3, 2GB of RAM, 32/64GB of storage and a 1280 x 768 pixel display. There should also be a 16 megapixel camera at the back with Full HD capture and want to add to the list LTE, NFC, a 5MP front camera, if possible and a 2.500 mAh battery. As you can see, the model runs Windows Phone 8, that includes those smaller tile sizes.

3. Surface Phone

The Surface Phone is very rounded and its profile seen from up looks like a hexagon. This device inaugurates a new way of multitasking, by rotating the phone and opening another task. There are also fully integrated bumpers, so the screens won't touch the ground. Other specs include 8 megapixel front and back cameras and the chassis is merely 8mm thick.a

2. BlackBerry Wind

BlackBerry Wind relies on a 1.5 GHz dual core processor, it has a camera button, a 4 inch LCD display with a 1024 x 600 pixel resolution and 4G LTE connectivity. It measures just 8mm in thickness and brings an 8 megapixel camera at the back, a 2 megapixel front camera and Gorilla Glass 2 protection for the screen. You also get stereo speakers and soft keys near the Windows Phone one with haptic feedback.

1. Nokia 8

Nokia 8 runs Windows Phone 8, with those smaller tiles, medium tiles and wider, bigger tiles. There's a 12 megapixel camera at the back and the device has at the bottom the audio jack, the microUSB port and a speaker grille, a design that may remind you of the iPhone 5. Up at the top there’s the earpiece and on/off button, while on the side we have the camera button and the volume buttons. The display is brilliantly integrated into the rectangular case of the Nokia WP8 concept.
